Here’s one I’ve been waiting for.
M104, The Sombrero Galaxy.
Until recently it’s been too low to target from my location.
I’ve tried a month ago but one of the buildings around me blocked it.
Gave it a shot last night and there it was!
It was breezy and that area of the sky has a lot of light pollution, so, I did the best I could at processing as much out as I could while preserving most of the details.

 

I can’t wait to revisit this one when my backordered ZWO ASI294 MC camera arrives.

M104-The Sombrero Galaxy

Orion Xtg10 goto Alt/Azimuth telescope
ZWO 178 MC camera
ZWO EAF focuser
1000x5 second subs
Captured in NINA
Processed in PixInsight, Photo Shop, and Topaz

Bortle 7

Nicely done!

Very nice indeed- I did a wider version with my RASA however I wanted to try with the C14 but the weather would not play nicely.

I downloaded your image and I was able to remove the gradient and produce a much sharper image which pulls out detail in the galaxy itself and before the naysayers complain that this is artificial detail- it has been bought out by APF-R which is used by NASA.

 

Let me know if you want me to post the improved image.

Nice.  What gain setting were you using?

Please post it!  I've only been at this Deep Sky processing for a few months and my skill level is just above advanced beginner.  Someone with more skill can show me what I could do with more practice.

Gain 350, no binning, offset 60.

Still working  on imaging and processing but here is my try at M104.  Astrotech 102 and ZWO 183MC Bortle 6/7 skies.

Good shot.  That's a lot better than I can see 104 in my Skywatcher 150, where it is just a faint fuzzy.

 

And even with an alt-azimuth mount.

Super nice.    Joe

A pleasure- I ask first before posting- 

 

The results you obtain would be better as I'm working with the JPEG file that you posted so it is not the same quality as your original data. You will have noticed I've removed the gradient as well as that was distracting from a very good image.

No joke.   WOW,   you did a great job  pyrasanth  processing.    KB,  that is one nice shot you took.   The swirls in top of the disc are really pronounced.    Really nice job to both of you.   Joe

Thank you Pyrasanth!  That really is much better.

I tried to purchase this plug in but it seems my version of Photoshop is not compatible, and the site wanted Creative Cloud to do the install, which i installed but it failed the installation.  I wish they would just allow the plugin file to be downloaded so I could attempt to do something with it, but no.

Agreed, this is some great data.  I continue to be impressed by what kb38758 is doing here -- big Dobsonian, oodles of short exposures.  It's clear that there's not one way to do deep-sky AP.  It's about skill, not just equipment.

Thanks EPinNC!  I'm only able to get fair to good results because of the big Dob.  It helps offsets the alt/azimuth tracking and camera weaknesses.  I DID order the ZWO 294 MC.  Backordered but coming some day.
